Well, obviously, if you have to ask someone else what style of alcohol is socially correct, you're necessarily a barbarian. If you weren't a barbarian, you'd know. ;p

The corollary is that you know you are not a barbarian when you can explain why someone else is a barbarian if they have to ask someone else what style of alcohol is socially correct ;)

FWIW, because I've just explained that you aren't a barbarian because you explained to someone they are a barbarian because they had to ask if their choice of alcohol is socially correct I exist in an indeterminate state of barbarism until I'm observed.
